Ray Ozzie, former Chief Software Architect at Microsoft, has decided that voice communication, in other words, the venerable phone call, is broken, and he’s going to fix it.

You get all sorts of added functionality, like the ability to tag certain parts of a conversation, share photos and text messages during a call, and access archives of old calls. The app is squarely aimed at businesses, and in particular teams that need to work together.
